Analyze Data

The unmanned folding wing aircraft has the advantage on expanding the flight envelope. The angle measurement algorithm of folding wing craft which based on MEMS (micro-electromechanical systems) accelerometers was studied. Collected the acceleration values from the accelerometers, and built the motion parameter model .Used the analyze data and the redundant acceleration; multiple sensors were used to do the error correction. With the experiment of folding wing, the validity and accuracy of the algorithm was verified.

Improve Accuracy

The current implementation of the synchro to digital conversion (SDC) can not directly detect harmonic which can cause the problem of low precision angle measurement. To improve accuracy of angle, harmonic interference was analyzed and summarized in the axis-angle to digital conversion process. Through detailed research, a new angle measurement formula is proposed in this paper, this formula can be very good for angle error correction and compensation. In order to meet the practical requirements, a software measurement method based on FFT algorithm of harmonic analysis and error correction is put forward. Matlab simulation shows that the formula and method is effective and feasible.
